The perivous graph represents the number of meales eaten in Fast Food restaurants and Sit-down restaurants between the 70s and early 2000s.
The graph shows that Fast Food meals are growing faster with the time, while the Sitdown restaurants are growing as well but in slower growth.
By mid 70s the number of meals eaten in Sitdown restaurants was 20 meals a year, that kept increasing to reach about 35 meals a year by 1980. The growth continued slowly in 1990, where the number of meals eaten per year reached 40 meal. We notice a minor increase by the end of the graph (2000), about 45 meals a year.
On the other hand, we got the Fast Food restaurants. Which shared the same starting point as the Sitdown restaurants, that is 20 meals a year by mid 70s. A decade later we see a small growth where it reached 25 meals a year. A major increase of the meals between 80s and 90s, where it went up to 50 meal a year, that growth kept getting higher, to reach it max by 2000, with almost 85 meal per year.
